Citrinin, a mycotoxin from Penicillium citrinum, plays a role in inducing motility of Paenibacillus polymyxa.
Paenibacillus polymyxa, a Gram-positive low-G+C spore-forming soil bacterium, belongs to the plant growth-promoting rhizobacteria. The swarming motility of P. polymyxa strain E681 was greatly induced by a secondary metabolite, citrinin, produced by Penicillium citrinum KCTC6549 in a dose-dependent manner at concentrations of 2.5-15.0 microg mL(-1) on tryptic soy agar plates containing 1.0% (w/v...
متن کاملAntimicrobial Activity of the Mycotoxin Citrinin Obtained from the Fungus Penicillium Citrinum
The mycotoxin Citrinin was obtained from the fungus Penicillium citrinum. It was tested for it's Minimum Inhibitory Concentration (MIC) against some gram positive strains viz. Staphylococcus aureus, Bacillus pumilus, Bacillus subtillis, Bacillus cereus, Klebsiella pneumoniae, Streptococcus pneumoniae, Lactobacillus arabinosus and gram negative strains E.Coli, Shigella dysenteriae, shigella sonn...
متن کاملCitrinin derivatives from the marine-derived fungus Penicillium citrinum.
Three new citrinin derivatives, penicitrinols C, D, and E (1-3), along with two known compounds, citrinin (4) and decarboxydihydrocitrinone (5), were isolated from Penicillium citrinum. Their structures were determined by spectroscopic methods and X-ray diffraction analysis. Compounds 1 and 3 demonstrated weak cytotoxicity against the HL-60 cell line.
متن کاملInhibition of Citrinin Production in Penicillium citrinum Cultures by Neem [Azadirachta indica A. Juss (Meliaceae)]
The efficacy of different concentrations of aqueous neem leaf extract (3.12 to 50 mg/mL) on growth and citrinin production in three isolates of Penicillium citrinum was investigated under laboratory conditions. Mycotoxin production by the isolates was suppressed, depending on the concentration of the plant extract added to culture media at the time of spore inoculation. Citrinin production in f...
متن کاملGenetic variability of citrinin-producing Penicillium citrinum strains as occupational health hazards in northern Iran.
We evaluated the ability of randomly amplified polymorphic DNA (RAPD) to type citrinin-producing Penicillium citrinum (P. citrinum) strains recovered from the forest's air in northern Iran. A total of 12 P. citrinum strains (P1-P12) were characterised by citrinin production and random amplification of polymorphic DNA (RAPD) technique. All the strains produced citrinin with levels ranging from 1...
